Which Harness, do you have, TRS or RR?
About you modifying it from what it came from the factory? Pls, let us know how that goes.

I've been waiting to see if someone would post about doing a total rewiring to make the LEDs permanent, sadly it doesn't look like that is coming any time soon and I will start going the harness route.
Does anyone have the gen 3 harness on a 2015 501A from TRS? That seems to be the best option right now but I need some piece of mind before I shell out $300...

for those of you who have forscan and are running either the rr or trs harness, try inputting the following values in the bcm
726-26-02 xxxx xxx0 xxxx - LED configuration.
Disable all lamp outages and clear all codes.
This seems to be a possible fix. Run on auto with drls

This was passed on to me by livnitup. My lights have been working flawlessly.
The other day I said I'd find out what the description for the following address/value is that seems to alleviate problems for guys doing the Halogen to OEM LED setup. This is the description that the other software I have states for this address bit.
726-26-02 xxxx xxx* xxxx - Frequency Select Cfg
Options:
0=Type 0 (default for factory LED)
1=Type 1 (default for factory Halogen)
2=Type 2
3=Type 3
I realize this description is vague but that's what it says so this is the description that will be added to the spreadsheet for consistency. I'm unsure what Type 2/3 do so I'll leave that up to others to experiment and post any observed differences.

Newbie question,
Should I go with the RR or the TRS/Morimoto harness? The RR seems to have less issues running the lights on AUTO with DRLs. TRS flat out says to switch the lights on/off manually. I want to run my lights on AUTO with DRLs just like I have my factory halogens.

They are both the same harness with morimoto components. I would honestly go with TRS. They are cheaper and you will get better customer service. If you call, they will also probably get your a coupon code to save a few extra
